I have at last solved the problems tuning my Panasonic HDD Recorder. After months of frustration i finally got around to retuning the HDD via the feed in my bedroom, which runs off of a seperate aerial and lead. The HDD tuned in perfectly. I re-connected the HDD downstairs and again had very bad /loss of signal. It wasn't until i wiggled the aerial coax input that i found the got bad then better. To cut a long story short, i cut about a foot off of my lead, attached a new coax plug and hey presto all are now tuned and functioning correctly. Thanks for all your advice!

The BBC (62) on has suddenly started breaking up for me, and judging by the variations in strength and signal qality mI am seeing, it is co-channel from a distant .

Can anyone by pointing me to a schedule which lists the dates of each of the changeovers and the on which the main transmitters transmit? I could then track down what might be the intefering station.

I could do it the long way (enterring postcodes appropriate to each main in the postcode checker) but I would have expected there was a listing somewhere.

Sorry for the typo.
"The BBC (62) on " should of course be "The BBC multiplex (61) on Mendip"

I have discovered your link Transmitters has Find by , and when I enter 61, I get shown all the transmitters transmitting on 61, and their (planned? actual?) changeopver dates.

The in Scotland started transmitting its BBC on on 22 July 2011, so it could be a candidate for causing the inteference with my .

But it broadcasts on only 10Watts. Is it feasible that a 10W signal from Scotland could cause co- inteference with a 100kWatt signal from Mendip? I normally receive Mendip 61 at 60% strength and 100% but I am now seeing it drop to as low as 40% strength and 10% quality.
All other Mendip multiplexes are OK so it is unlikely it is my etc.

There is no work reported on Mendip.

Any thoughts will be appreciated!

John-Ha: If you could provide a full postcode it would be possible to you out with your issues. It is not very likely you would be able to receive a signal from Scotland, even during the Inversion conditions.
